Extracting Vibration Characteristics Of A Guitar Using Finite Element, Modal Analysis, And Digital Image Correlation Techniques, Kiran Patil, Javad Baqersad, Daniel Ludwigsen, Yaomin Dong

Physics Publications

The sound quality generated by the guitar depends on the vibration characteristics (i.e. natural frequencies and mode shapes) of this instrument. Thus, it is of particular interest to the guitar manufacturers to be able to obtain global information about the characteristics of the guitar. Traditional sensors can only measure at discrete locations. However, digital image correlation (DIC) can measure full-field data on the surface of the structure. In the current paper, a finite element (FE) model of a guitar with free boundary configurations was developed using quadratic solid elements. An eigensolution was performed on the FE model to determine its …

Overview Of Lte Spectrum Sharing Technologies, Yun Ye, Dalei Wu, Zhihui Shu, Yi Qian

Department of Electrical and Computer Engineering: Faculty Publications

Long-Term Evolution (LTE) communication systems feature advanced frequency reuse and interference coordination techniques providing faster and more secured mobile services. However, the network capacity in licensed spectrum is still behind market demands. Dynamic spectrum access or spectrum sharing in other frequently vacant or unlicensed frequency bands is considered an effective means to boost system throughput. Different from operations in licensed spectrum with exclusive access, LTE deployment needs to take into account the distinct regulations on channel access to each shared frequency band, in order to avoid interference to incumbent users, and to maintain fair play with peer operators in heterogeneous …

Chauhan, Keehoon Jung, John D. Martin, Vasileios Askoxylakis, Timothy P. Padera, Dai Fukumura, Yves Boucher, Francis J. Hornicek, Alan J. Grodzinsky, James W. Baish, Lance L. Munn, Rakesh K. Jain

Faculty Journal Articles

olid stress and tissue stiffness affect tumour growth, invasion, metastasis and treatment. Unlike stiffness, which can be precisely mapped in tumours, the measurement of solid stresses is challenging. Here, we show that 2D spatial maps of the solid stress and the resulting elastic energy in excised or in situ tumours with arbitrary shapes and a wide range of sizes can be obtained via three distinct and quantitative techniques that rely on the measurement of tissue displacement after disruption of the confining structures. Application of these methods in models of primary tumours and metastasis revealed that (i) solid stress depends on …

On Rational Subgroups Of Exceptional Groups., Neha Hooda Dr.

Doctoral Theses

The main theme of this thesis is the study of exceptional algebraic groups via their subgroups. This theme has been widely explored by various authors (Martin Leibeck, Gary Seitz, Adam Thomas, Donna Testerman to mention a few), mainly for split groups ([26], [27], [28], [60] ). When the field of definition k of the concerned algebraic groups is not algebraically closed, the classification of k-subgroups is largely an open problem. In the thesis, we mainly handle the cases of simple groups of type F4 and G2 defined over an arbitrary field. These may not be split over k. We first …

Robustness Of The Potential And Flux Landscapes In Fission Yeast Cell Cycle Networks, Xiaosheng Luo

Theses and Dissertations

Using fission yeast cell cycle as an example, we uncovered that the non-equilibrium network dynamics and global properties are determined by two essential features: the potential landscape and the flux landscape. While potential landscape quantifies the probabilities of different states forming hills and valleys, the flux landscape quantifies the probability fluxes of different loops flowing through states. These two landscapes can be quantified through the decomposition of the dynamics into the detailed balance preserving part and detailed balance breaking non-equilibrium part. While the funneled potential landscape is often crucial for the stability of the single attractor networks, we have uncovered …

Theses and Dissertations

The economic interest in Rare Earth Elements (REEs) has directed research into the REE content of fresh Combustion Products (CCPs). CCPs are the solid waste produced by coal combustion, which have been noted to weather rapidly in holding ponds to clays that are known to bind up REEs. Sequential leaching experiments using a modified version of Tessier et al. 1979 method were performed to determine the chemical association of the REE content in fresh and weathered CCPs. The leachate of each step was analyzed through ICPMS to determine the REE content in each fraction of the CCP material. Morphological changes …

Attitudes Of Advanced Placement Teachers Toward Debate: Meeting The 21st Century Critical-Thinking Needs Of Gifted Secondary Students, Allison Mcmath Mcmath

Theses and Dissertations

Young Americans must be equipped, both individually and collectively, with the 21st century skills, critical thinking, communication, collaboration, and creativity, in order to thrive in the global landscape which lies before them. Little political or economic capital is devoted to maximizing academic opportunities for gifted secondary learners. Limiting opportunities for children and youth with the potential for performing at remarkably high levels of accomplishment, deprives them of their right to an appropriate education and wastes a national resource. Recognizing that limited capital often circumscribes schools in their ability to provide special programs, the researcher proffers debate, a course within the …

River Otter (Lontra Canadensis) Distribution And Habitat Suitability In Nebraska, Nathan R. Bieber

School of Natural Resources: Dissertations, Theses, and Student Research

River otters (Lontra Canadensis) were extirpated in Nebraska by the early 1900’s, but in 1986, the Nebraska Game and Parks Commission (NGPC) began reintroduction efforts. Following reintroductions, the otter was listed as a tier-1 at-risk species in Nebraska. With increasing otter populations, NGPC is evaluating a de-listing plan. In order to inform de-listing efforts, I surveyed Nebraska’s rivers documenting otter sign and used modeling techniques to estimate otter distribution and habitat suitability.

Otter sign surveys were conducted on the navigable rivers of Nebraska. Occupancy modeling techniques were used to examine patterns in otter detections. The best model incorporated distance …

Synthesis And Carbonation Of Nanocrystalline Fayalite (Fe2sio4), Joshua Manley

Theses and Dissertations

The limited availability of fayalite on Earth has led to the use of synthetic fayalite in studies requiring iron rich olivine. The method presented in Part II is a novel modification of previous sol-gel techniques that produced nanofayalite. This new method uses a different set of reactants that eliminates several steps from the previous method, thus saving time while producing a similar result. Presented in Part III is a scoping experiment investigating carbonation of nanofayalite using slight modification from techniques of previous studies involving nanoforsterite. No previous studies have examined the carbonation of nanofayalite. While it is expected that experimental …

Using Geochemistry And Strontium Isotopic Ratios (87sr/86sr) To Determining Water Mixing And Sources In The Picher Mining District, William Daniel Ketcheside

Theses and Dissertations

The mining of lead and zinc ores in the Tri-State Mining District of Kansas, Missouri, and Oklahoma resulted in some of the most severe environmental degradation in the country. Large amounts of waste rock, known as ‘chat’, were produced during mining and left in surface piles in the surrounding area. These chat piles, located mostly near the town of Picher, Oklahoma contain potentially harmful elements that can be leached from the rock into local streams and sediment. The mines also filled with water after mining ceased and have discharged contaminated water to nearby waterways, as well as resulted in groundwater …

Adaptive Classification Framework For Control Myoelectric Prostheses During Muscle Fatigue, Hamdi Allbunashee Allbunashee

Theses and Dissertations

A myoelectric-controlled prosthesis holds the promise of renewed quality of life for the amputee population. When it comes to prosthesis control, muscle fatigue presents a significant challenge for all task discrimination algorithms due to changed muscle activation patterns and significant shifts in the spectral contents of the surface electromyogram (sEMG) signals. The effect of muscle fatigue on the classification accuracy of two supervised machine-learning algorithms, i.e. the linear discriminant analysis (LDA), and the muscle synergy based task discrimination (MSD) was investigated. Due to muscle fatigue, the classification accuracies declined from (>90%) to 41% and 59% for the LDA and …

A Family Of Optimized Lms-Based Algorithms For System Identification, Silviu Ciochinǎ, Constantin Paleologu, Jacob Benesty, Steven L. Grant, Andrei Anghel

Electrical and Computer Engineering Faculty Research & Creative Works

The performance of the least-mean-square (LMS) algorithm is governed by its step-size parameter. In this paper, we present a family of optimized LMS-based algorithms (in terms of the step-size control), in the context of system identification. A time-variant system model is considered, and the optimization criterion is based on the minimization of the system misalignment. Simulations performed in the context of acoustic echo cancellation indicate that these algorithms achieve a proper compromise in terms of fast convergence/tracking and low mis adjustment.
